HDA-4500  1.485 Gb/s HD 6 O/P Distribution Amplifier

Features

Applications:

• Link selectable for either High Definition or Standard Definition digital signals

• 6 non reclocked outputs

• Automatic input equalisation

• Signal presence LED and external relay alarm contact

• Optional plug-in SNMP monitoring module

General

The HDA-4500 1.485 Gb/s serial digital video distribution amplifier provides the user with a single standard module to cover a wide range of distribution and monitoring functions for High Definition (HD) digital signals.
As well as accepting an HD signal, the HDA-4500 will also accept Standard Definition (SD) rates such as SDI. ASI is also possible, however as three of the six outputs are inverted only the non-inverted output ports are suitable for ASI.
Serial digital signals suffer severe deterioration over relatively short cable distances. This is especially so with the HD high data rate. The HDA-4500 provides a means of extending the working distances that can be achieved by equalising and re-transmitting the data mid route.
An on board link sets whether the HDA-4500 will accept a either 1.485 Gb/s HD signal or a lower rate SD signal by adjusting the output driver slew rate to suit.

Front panel LEDs indicate when an input signal is present and also whether the on board link is set for HD or SD operation.
A relay alarm output, with a selectable N/O or N/C switch to ground contact, is available for indication of loss of input signal or loss of power.
An optional SNMP (Simple Network Management Protocol) plug in module is available for remote monitoring when used in conjunction with IRT's 4000 series frame fitted with SNMP capability.
The HDA-4500 is designed to fit IRT's 4000 series frame for use with IRT's SNMP system as well as being suitable with IRT's Standard 1000 and 3000 series Eurocard frames and may be used alongside any other of IRT's analogue or digital Eurocards.

HDA-4521  Dual 1 In, 3 Out HD/SD Reclocking Distribution Amplifier

Features

• 3 non inverting outputs on each amplifier.

• Link selectable for 1 in, 6 out single distribution amplifier operation.

• 3 Automatic reclocking of High Definition or Standard Definition digital signals.

• Input equalisation > 100 m for HD, > 250 m for SD.

• Automatic output muting on no input.

• Front panel signal presence LEDs and external alarm contacts.

• Optional plug-in SNMP monitoring module.

  General

  The HDA-4521 HD/SD dual serial digital reclocking video distribution amplifier provides the user with a single standard module to cover a wide range of distribution and monitoring functions for High Definition (HD) and/or Standard Definition (SD) digital signals. Two triple output reclocking distribution amplifiers are provided on the one card.
  As well as accepting HD or SD signals, the HDA-4521 will also accept ASI signals. To provide for the ploarity sensitive nature of ASI signals, all outputs of the HDA-4521 are in phase with the inputs.

  Serial digital signals suffer severe deterioration over relatively short cable distances. This is especially so with the HD high data rate. The HDA-4521 provides a means of extending the working distances that can be achieved by equalising and retransmitting the data mid route.

  The HDA-4521 will automatically reclock either 1.485Gb/s HD signals or lower rate 270Mb/s SD signals. Both sides of the HDA-4521 can be run independently allowing a mixture of signal types to be used.

  On board link settings allow either of the inputs to feed all outputs to create a one in, six out distribution amplifier.

  Front panel LEDs indicate when an input signal is present and whether the output is an HD or SD type.

  Separate alarm outputs switch to ground for indication of loss of input signal or loss of power.

  An optional SNMP (Simple Network Management Protocol) plug in module is available for remote monitoring and control when used in conjunction with IRT's 4000 series frame fitted with SNMP capability. Extra features are available via SNMP such as automatic switching on loss of one input to the other input.

  The HDA-4521 is designed to fit IRT's  4000 series 3RU frames for use with IRT's SNMP system as well as being suitable with IRT's 1000 series 1RU Eurocard frames and may be used alongside any other of IRT's Eurocards.
